Cops are searching for a graffiti vandal suspected of threatening a Queens councilman, The Post has learned.

Sources said a man identifying himself as Cope2, Fernando Carlo’s tag name, called Councilman Peter Vallone Jr. and left a message filled with expletives and an ominous warning:

“We don’t live forever.”

The message also said, “I don’t care, send the cops.”

“This comes with the territory,” Vallone said.

“Anyone who would destroy property is a criminal, not an artist.”

Police sources said cops are trying to confirm whether Carlos, who has been arrested 10 times for harassment and once for assault, was the person who made the call.

Vallone has been vocal in trying to stop Marc Ecko Enterprises from holding a block party in Chelsea this month. It would include 10 replica subway cars that graffiti writers, including Carlo, would paint.

Carlo was once paid $20,000 by Time magazine to paint graffiti on a billboard ad.
